PRESERVE WHEAT SEED FREE FROM KARNAL BUNT DISEASE: PAU
LUDHIANA, MAY 9:
The plant pathology expert of Punjab Agricultural University (PAU) has appealed to the farmers of Punjab to preserve wheat seed, free from karnal bunt disease, for the next sowing season.
As per Dr P.S. Sekhon, Head, Department of Plant Pathology, PAU, the newly recommended PAU varieties including PBW 677, PBW 725 and HD 3086 give 2-3 quintal more yield than the old variety HD 2967. While preserving wheat seed for the next crop season, care must be taken that the seed of these varieties should be free from karnal bunt disease, he said. About its symptoms, Dr Sekhon said the infected grains give out black powder of spore mass on pressing. This powder gives peculiar stinking smell, he added. Observing that the diseased seed can further increase the problem, he advised the farmers to go for seed inspection before preserving the seed. For seed inspection, soak handful (two) of wheat seeds in water for few minutes and then take the out the seeds and spread these on a white paper. In case 4-5 wheat seeds are found infected with karnal bunt, then don’t preserve the seeds, he told. Dr Sekhon stressed on the farmers to follow this method of seed inspection for selecting disease free seed.
